When Server Binding is Not Possible

In extreme cases where local server binding is not possible, use of
the ypset command can temporarily allow binding to another
server, if available, on another network or subnet. However, in order to use
the -ypset option, ypbind must be started
with either the -ypset or -ypsetme options.
For more information, see the ypbind(1M) man
page.

For security reasons, the use of the -ypset and -ypsetme options should be limited to debugging purposes under controlled
circumstances. Use of the -ypset and -ypsetme options
can result in serious security breaches because while the daemons are running,
anyone can alter server bindings causing trouble for others and permitting
unauthorized access to sensitive data. If you must start ypbind with
these options, once you have fixed the problem you should kill ypbind and
restart it again without those options.
